Prestashop Repository not found

Question

Good morning.

i have a problem using the new Symfony architecture. i created a modern controller where routing is working perfect. now i want to search products with ProductRepository.

MyModule/src/Repository/ProductRepository

namespace PrestaShop\Module\MyModule\Repository;

use Doctrine\DBAL\Connection;

class ProductRepository
{
/**
 * @var Connection the Database connection.
 */
private $connection;

/**
 * @var string the Database prefix.
 */
private $databasePrefix;



/**
 * @param int $langId the lang id
 * @return array the list of products
 */
public function findAllbyLangId(int $langId)
{
    $prefix = $this->databasePrefix;
    $productTable = "${prefix}product";
    $productLangTable = "${prefix}product_lang";

    $query = "SELECT p.* FROM ${productTable} p LEFT JOIN ${productLangTable} pl ON (p.`id_product` = pl.`id_product`) WHERE pl.`id_lang` = :langId";
    $statement = $this->connection->prepare($query);
    $statement->bindValue('langId', $langId);
    $statement->execute();

    return $statement->fetchAll();
 }

}

MyModule/config/services.yml

services:
   product_repository:
   class: PrestaShop\Module\MyModule\Repository\ProductRepository
   arguments: ['@doctrine.dbal.default_connection', '%database_prefix%']

MyController

$products = $this->get('product_repository')->findAllByLangId(1);
dump($products);

Now i get the following error: "Attempted to load class "ProductRepository" from namespace "PrestaShop\Module\MyModule\Repository". Did you forget a "use" statement for another namespace?"

What im missing there? Thx for your time and help.

update - Stacktrace:

It's look like you didn't create composer.json file with predefined namespaces.

Here example:

{
  "name": "YourName/YourModuleName",
  "description": "Awesome description",
  "autoload": {
    "psr-4": {
      "YourName\\YourModuleName\\": "/",
      "YourName\\YourModuleName\\Repository": "src/Repository/",
    }
  },
  "config": {
    "prepend-autoloader": false
  },
  "type": "prestashop-module"
}

OR if you want with Prestashop right way

{
  "name": "YourName/YourModuleName",
  "description": "Awesome description",
  "autoload": {
    "psr-4": {
      "Prestashop\\Module\\YourModuleName": "src/",
      "Prestashop\\Module\\YourModuleName\\Repository": "src/Repository/",
    }
  },
  "config": {
    "prepend-autoloader": false
  },
  "type": "prestashop-module"
}

Then run composer install and add to your YourModuleName.php file require_once.

$autoloadPath = __DIR__ . '/vendor/autoload.php';
if (file_exists($autoloadPath)) {
    require_once $autoloadPath;
}
